stapel-video

Video calls for the Stapel framework — a thin, provider-agnostic library over a real-time video backend (LiveKit by default).

Rooms with human-shareable join codes (abc-defg-hij).
Admission model — public (anyone with the code joins), scope_trusted (members of the room's scope join instantly, others wait), restricted (everyone but the host waits in a lobby).
Realtime lobby over WebSockets (Channels) — waiting / admitted / denied, authenticated by the same Stapel JWT stack HTTP uses.
Host controls — admit / deny waiting guests.
Provider seam — one VideoProvider ABC (mint join token, create room, start/stop recording egress, verify webhook). Swap vendors without forking.
Recording is a seam, not a pipeline: start/stop_egress proxy the provider and a video.egress_ended comm event carries the storage key to stapel-recordings — by event, never by import.

Alpha (0.1.0). See MODULE.md for the agent-facing map of seams.

Install

pip install stapel-video            # core library
pip install 'stapel-video[livekit]' # + the default LiveKit backend
pip install 'stapel-video[channels]'# + the realtime lobby (WebSockets)

Mount

# urls.py
path("video/", include("stapel_video.urls"))

# asgi.py (realtime lobby)
from channels.routing import ProtocolTypeRouter, URLRouter
from stapel_core.django.jwt.channels import JWTAuthMiddlewareStack
from stapel_video.routing import websocket_urlpatterns

application = ProtocolTypeRouter({
    "http": django_asgi_app,
    "websocket": JWTAuthMiddlewareStack(URLRouter(websocket_urlpatterns)),
})
